* Fixed an issue during interim cache updates (fully updates are performed daily) where the incorrect OutputUnits were identified for the InstrumentSensivity information. As this condition only sometimes occurs when metadata is updated and is then fixed during daily updates the issue was unlikely to effect more than a few (if any) users.
* Fixed a bug related to Poles & Zeros where they are skipped if no poles and zeros exist for that particular stage. Sometimes network operators use an “empty” Poles & Zeros blockette to describe a unit conversion, usually as part of a stage describing a digitizer. The missing information should not have effected metadata usage but makes the metadata more complete.
This release is backwards compatible with all request tools.
